Solution Overview
Problem
Conventional grinders for coffee beans are not suited for grinding tea leaves, leading to inefficient grinding, incorrect powder quantity, and environmental pollution due to the need for packaging, which affects the flavor and nutrient content of brewed tea.
Innovation Solution
A grinder with a main casing, grinding assembly, and unloading assembly that includes a measuring barrel and partafilter, allowing for precise grinding and collection of brewing materials like tea leaves, reducing the need for packaging and ensuring fresh, nutrient-rich brewing powders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional coffee grinders are used to grind tea leaves, then the grinding mechanism can be utilized, but the grinding efficiency is low and the powder quantity cannot be controlled accurately
Solution Approach 1:
The invention divides the grinding chamber into an upper grinding chamber and a lower collection chamber separated by a filter. The upper chamber contains the grinding mechanism while the lower chamber collects the ground powder. This segmentation allows for efficient grinding in the upper chamber while simultaneously enabling precise measurement and control of the powder quantity in the lower chamber, resolving the contradiction between grinding efficiency and powder quantity control.
Solution Approach 2:
A filter is introduced as an intermediary component between the grinding chamber and the collection chamber. The filter allows ground powder to pass through while retaining larger particles, ensuring that only properly ground material is collected. This intermediary mechanism enables accurate powder quantity control and measurement while maintaining high grinding efficiency in the upper chamber.
2Ease of manufacture
If tea leaves are ground into powder and packaged in small bags, then the powdered tea can be stored and transported, but environmental pollution increases and packaging costs rise
Solution Approach 1:
The invention extracts the harmful packaging element (small bags) from the system by implementing a direct collection mechanism. The ground powder is collected directly in the lower collection chamber where it can be dispensed as needed without requiring individual packaging. This eliminates the need for small bags, reducing environmental pollution while maintaining storage and transport convenience through the integrated collection chamber.
Solution Approach 2:
The invention merges the grinding function and the collection/storage function into a single integrated device. The upper grinding chamber and lower collection chamber work together as one unit, allowing the ground powder to be collected and stored without requiring separate packaging materials. This merging eliminates the need for additional packaging while maintaining the convenience of having pre-ground powder available.
3Ease of operation
If powdered tea is stored for later use, then convenience is improved, but the powder absorbs moisture and spoils more easily than whole leaves
Solution Approach 1:
The invention prepares the ground powder in advance in a controlled environment (the sealed lower collection chamber) and keeps it there until needed. The powder is ground and collected in one operation, then stored in the sealed chamber without exposure to moisture or air. This preliminary preparation followed by immediate sealed storage maintains powder freshness while providing the convenience of having pre-ground powder ready for use.
Solution Approach 2:
The lower collection chamber acts as a flexible seal that contains the ground powder and protects it from moisture and air contamination. The sealed chamber design allows the powder to be stored for later use while maintaining its freshness, resolving the contradiction between convenience of pre-ground powder and reliability of powder quality.
4Manufacturing precision
If the grinder is designed specifically for tea leaves, then grinding effectiveness is improved, but the device loses versatility for other brewing materials
Solution Approach 1:
The invention designs the grinding mechanism with adjustable parameters and a universal structure that can handle different types of brewing materials. The upper grinding chamber and filtering system are configured to accommodate various materials such as coffee beans, tea leaves, and herbs while maintaining effective grinding performance. This universal design allows the device to be adapted to different materials without sacrificing grinding effectiveness, resolving the contradiction between specialization and versatility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The grinder provides fresh, nutrient-rich brewing powders with precise quantity control, eliminating the need for packaging and reducing environmental pollution, while ensuring accurate grinding of tea leaves and other materials.
Implementation Method 1
a grinding assembly (30) to grind the brewing materials into brewing powders
Implementation Method 2
the brewing powder drops into the unloading assembly to be collected. When the unloading motor actuates the measuring barrel rotates, the brewing powder is deposited in a partafilter

AI summary
A grinder for preparing brewing materials has a main casing, a grinding assembly and an unloading assembly to measure the amount of the brewing powder to unload. The unloading assembly has an unloading motor and a measuring barrel. When the user puts the brewing materials into the main casing, the grinding assembly grinds the brewing materials into the brewing powder. The brewing powder drops into the unloading assembly. When the unloading motor actuates the measuring barrel rotates, the brewing powder is deposited in a partafilter. Therefore, a user can grind tea leaves, Chinese herbal medicine, the petals and so on to have fresh brewing powder. Brewing liquids with the fresh brewing powder keeps the nutrient content and flavor. In addition, the bags for packaging the brewing powder is no longer needed to reduce environmental pollution and packaging cost.
